每日一練:下列可使兩個直角三角形全等的條件是

更新時間:2024-01-12 12:54:36作者:貝語網校

下列可使兩個直角三角形全等的條件是

A.一條邊對應相等

B.斜邊和一直角邊對應相等

C.一個銳角對應相等

D.兩個銳角對應相等

試題答案

B

試題解析

根據已知及全等三角形的判定方法進行分析,從而得到答案.

解答:A、錯誤,全等的兩個直角三角形的判定只有一條邊對應相等不行;

B、正確,符合判定HL;

C、錯誤,全等三角形的判定必須有邊的參與;

D、錯誤,全等三角形的判定必須有邊的參與;

故選B.

點評:本題考查三角形全等的判定方法,判定兩個三角形全等的一般方法有:SSS、SAS、ASA、AAS、HL.

注意:AAA、SSA不能判定兩個三角形全等,判定兩個三角形全等時,必須有邊的參與,若有兩邊一角對應相等時,角必須是兩邊的夾角.
